オオスズメバチに刺されても平気！？

トノサマガエルは、実験室下でキイロ、コガタ、オオスズメバチの働き蜂を襲い、それぞれ93%、87%、79%の高い頻度で捕食に成功。攻撃中、何度も刺されるも、死傷したカエルはなし。毒針に対して高い耐性をもつ可能性がある。

Day 2 of #ArtAdventCalendar & I'm going with a piece that still makes me go 'blimey did I actually do that', created as part of BirbFest this year in Jan. It's one of those ones where you loose time while making and then surprise yourself when it's finished!

#BirdArt #SciArt #Cassowary #Procreate
An original digital illustration of a Cassowary bird by Loadofolbobbins. The illustration focuses on its neck and head. A very dinosaur looking bird the Cassowary has a bright reddish orange wrinkled neck and wattle that transitions to a bright intense blue face with sharp angles of the skull visible underneath its skin. It has a beak slightly elongated and pointed downwards. It has a large eye with a yellowy orange iris that is glistening in the sun. On top of its head is a casque, which is an enlargement of the bone from its upper skull and looks almost like a Mohawk and is an array of greens in colour. The background is a splash of light grey ink.

I've made some smaller beanie versions of the Devonian jawless fish - Zenaspis!

At 25cm long, these are lifesize! www.palaeoplushies.com/shop/zenaspis

I ship worldwide from the UK, US tariffs collected and pre-paid for easy delivery!
A collection of 3 realistic plushie jawless fish, Zenaspis. They have horseshoe shaped heads with pointy tails emerging from the back of them. Their beady eyes shine grey or gold. They are patterned cryptically and come in shades of brown and blue.

『生物学を進化させた男 エドワード・O・ウィルソン』読了。
ダーウィンやドーキンスやグールドに比べても微妙に知名度が低いかもだが、アリの研究から「社会生物学」を発展させた、20世紀屈指の生物学者エド・ウィルソンの人生を綴る一冊。

「物理学以外の科学は、ただの切手収集だ」などという乱暴な格言もあるが、ウィルソンは「切手収集ナメてんじゃねーぞ」と言いながら（いや言ってないがそういう気概で）アリという特定の分類群の研究を深め、領域ごと格上げに挑んだ。生物学を学ぶ営みのアツさに満ちた本。
（著者は『エネルギー400年史』等のリチャード・ローズで、名ジャーナリストらしい精緻な書きっぷりで読み応えある）

Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶
Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.

As I've done the past couple years, I'll be posting my favorite images from 2025 throughout December, one a day. Here's a close image of a little blue heron with a green tree frog who's fighting for dear life, trying to pry open its beak. #birds

イエネコの中国への伝来は従来考えられていたよりも遅く、唐代にシルクロード経由でもたらされた。それ以前の時代の遺跡から見つかる小型ネコはすべてベンガルヤマネコで、5400年前から3500年にわたり片利共生が続いた。中国でのイエネコとヒトの歴史はまだ、ベンガルヤマネコとヒトの歴史の半分にも満たない（！）

グアテマラの熱帯雨林に同所分布するネコ科4種の食性の違い。糞内容物への出現率で、ジャガーはペッカリーとアルマジロが突出して高く、ピューマはジェネラリストだがシカよりサル（クモザル・ホエザル）を多く食べている。オセロットとマーゲイはどちらもオポッサムと齧歯類が中心だが、マーゲイはそれぞれの樹上性種をより頻繁に捕食。オセロットはジャガーにかなり捕食されているが、空間的回避はしていない phys.org/news/2025-11...

Sequence of camera trap photographs of songbirds on a forest floor. In the topmost photo, two birds are shown in a single photo, whereas the remaining photos show a single bird each. The birds have grayish bodies and black-and-white faces, with a brown "hood" on the top of the head and neck.

What might be my favourite fossil has been just published by Kiat et al. 2025. Years ago I saw a pic of this Anchiornis specimen in nat geo article and I audibly gasped.preserving not only the feathers but also the original patterns as well. I made this drawing on the spot. Maybe its time to do v2.0
